The principal objects which the present invention has in view are:-to beenabled through utilization of two strips of material to shape the sameto simulate an improved milk bottle and 5 the like; to be enabled tomake containers of var ious shapes; to provide means to reduce to aminimum leakage of liquids through the bottom of the completedcontainers; to be enabled to manufacture the containers in a singleoperation;

1' to be enabled to'ship various shaped containers in a common cartonand to utilize minimum space; to secure simplicity of construction andoperation in the manufacture of the containers; and to obtain otheradvantages and results as 18 may be brought out in the followingdescription.

In the drawings:-

Figure l is a schematic view showing the initial relation of flat sheetblanks from which the container is constructed;

Figure 3 is a vertical sectional view of the same shown as taken on theline 3-3 of Figure 2;

Figure 4 is a similar view and showing the upa per part of the containerin completed condition;

Figures 5 and 7 are similar views and showing the lower part of thecontainer shaped to embody features of the present invention with Figure5 shown as taken on the line 55 of Figure 6;

, Figures 6 and 8 are top and bottom plan views of the same;

Figure 9 is an enlarged fragmentary sectional view of the lower part ofthe container wherein features of the present invention are shown indetail and taken on line 9-9 of Figure 6;

Figure 10 is an enlarged transverse sectional view shown as taken on theline Ill-l0 of Figure '7;

Figures 11 and 12 are enlarged side elevational 40 views of thecompleted container, Figure 12 being shown as of a slightly diiferentconstruction; and Figure 13 is a plan of a shipping container andshowing containers constructed in accordance with the present inventionpacked therein. 5 As will be seen in the drawings, and referring toFigure 1, the present invention is more particularly directed toconstruction of containers, such as bottles and the like to simulate theappearance and purpose of a conventional milk 50 bottle, and to bemanufactured of various shapes and sizes. Having this in mind, there aretwo blanks of sheet metal or paper. The blank indicated by the numeralI5 is arcuate in form constituting a segment of an annular strip. The.15 edges l6 and ll of said blank l5 are concentric.

- ture-proof paper, especially when the completed 19 at the edge 20thereof is equal to the length of the longer arcuate edge ll of thefirst mentioned blank I5. Both the top and bottom margins 20 and 2| ofblank l9 are provided with an adhesive thereon as indicated at 22 and 23re 10 spectively. The upper strip of adhesive 22 preferablyonly extendshalf the length of the blank, in view of the fact that the blank is, inthe present disclosure, of sufiicient length to wrap twice about amandrel and thus bring the adhesive between the two plies of materialand leave the inside face of the bottle clear of any adhesive. It mayhere be noted that the material comprising blanks l5 and I9, if paper,is preferably a prepared moisbottle is to be used for liquids.

With the two blanks l5 and I9 formed'as shown, the marginal area nextthe longer arcuate edge I! of the upper blank I5 is overlapped upon themarginal edge next to the upper long I edge of the lower blank l9, andthe two blanks 5 then folded around a mandrel, .the lapping mar-- ginshaving adhesive therebetween and being forced into juxtaposition,pressed one upon the other and caused to tenaciously adhere forming thesections into the body portion of the bottle.

While the specificstructure of this body portion of the bottle has beenshown, and therefore described, as composed of two sections securedtogether, it will be understood that the invention is not limited tothis specific formation or number of parts, as the body portion may aswell be madeof one piece and on the other hand may be made of more thantwo pieces. Inany event, the overlapping vertical ends of the blank or40 blanks are secured by vertical strips of adhesive 24 to both keep theblanks from unwinding and for sealing the vertical seam against egressof the contents of the bottle.

An important feature of the present invention resides in the fact thatthe body portion of the bottle is made, in cross-section, of anappropriate shape enabling a plurality of bottles to be placed side byside, for instance in a shipping container C, with a minimum of wastespace between the bottles. In Figures 5 to 10, 'and at the left ofFigure 13, as designated by character A, bottles have been illustratedwhich are substantially triangular in cross-section, having roundedvertical edges, whereas Figures, 11 and 12, and the. right hand side ofFigure 13 as designated by character B, illustrate bottles which arerectangular in cross-section, these also having rounded verticalcorners. The invention is not limited to 5 these specifically selectedshapes, but other crosssectional shapes which will be conducive to closepacking and minimum waste space may be substituted.

A further important feature of the present invention resides in theformation of the bottom of the container and in the means and method offorming and connecting the bottom wall with the peripheral or side wallof the body portion of the bottle. As has already been described, thebottom margin 2| of the body portion has a strip of adhesive 23 thereon.This margin is reflexed, that is to say, is bent upwardly within thebody portion, as shown more particularly in Figures 7 and 9. The bottomwall 25 has its marginal edge or rim 26 turned downwardly, this rimconstituting a flange: having a depth preferably equal to the reflexedmargin 2| and is positioned between the reflexed margin and the mainbody portion. The parts will therefore cooperate, one to support theother, and thus provide a substantially rigid bottom edge for thebottle. It is to be understood that the shape of the bottom wall 25 whenviewed in plan, has the same shape and external dimension as theinternal shape and dimension of the lower part of the body portion ofthe bottle so there will be a perfect fitting between these parts. Theadhesive 23 on the lower section of the body portion will be toward andjuxtaposed upon the rim of the bottom wall, and aifords a tight sealingfor the bottom of the bottle besides retaining the bottom wall frombeing inadvertently pushed in while in use.

If so desired, the reflexed margin 2| may be corrugated vertically as at21 or otherwise to both increase its strength and radial pressureoutwardly against the rim 26 for a frictional holding contact therewith.The corrugations which consist of alternate grooves and ridges disposedparallel to the axis of the containers may likewise be impressed intothe juxtaposed face of the rim 26, if so desired, thereby increasing thesecurity between the parts, frictional expansive contact with the mainwall of the container, and strength of the bottom edge of the bottle.The corrugations may even be impressed in the juxtaposed inner face ofthe main part of the body portion next the outside periphery of the rim26, all of which is clearly shown in the crosssection of Figure 10. Aneffective method of assembly of the bottom wall with respect to the sidewall of the bottle consists in first corrugating the rim 26 of thebottom wall before insertion of the bottom wall thus corrugated, the'bottom margin 2| of the side wall would be refiexed into position andthen given a radial or side thrust pressure to unite the parts. Thisside thrust pressure is preferably accomplished with a corrugating toolby which the reflexed rim will be seated into the corrugations,previously formed, in the rim 26. This method of assembly isdistinguished from known previous methods where the bottom edge of thebottles are spun up and over.

I claim:-

A container comprising a body having upper and lower sections, the lowersection having a plurality of upright flat sides, and the upper sectionhaving a corresponding number of flat sides each of which tapers to asmaller dimension peripherally of the bottle next the top thereof, eachof said flat sides being connected by rounded vertical corners.
